Is Miir’s 32 Ounce Howler the perfect bottle for transporting your craft beer? Close to it, anyhow. These handy howlers are made of double-walled stainless steel for a vacuum-insulated seal that keeps cold things cold for upwards of 24 hours, or hot things hot for up to twelve. They also sport sleek clamping caps sealed with food grade silicone that are guaranteed leak-proof even when filled with carbonated beverages, and remain extremely easy to clean thanks to their threadless design. Available in two color options, either raw stainless or rugged powder coated black. For more information, follow the link below.
